The Huawei FreeBuds SE 4 ANC are in-ear wireless headphones designed for a balanced listening experience, featuring 10 mm dynamic drivers that cover a frequency range from 20 Hz to 20 kHz. They utilize Bluetooth 5.4 for stable connectivity and include multi-mode active noise cancellation alongside dedicated call noise reduction to help you stay focused on your audio or conversations in busy environments. Constructed from PC with soft silicone ear tips, each earbud weighs just 4.3 g, making them comfortable for extended wear. The IP54 water resistance rating protects the earbuds against splashes and dust, though this protection does not extend to the charging case. You can manage your music and calls through touch controls, using double-taps for playback and triple-taps to skip tracks, while holding the sensor allows you to adjust volume or switch noise cancellation modes. Battery life is substantial, offering up to 10 hours of music on a single charge with ANC off, extending to 50 hours when using the 510 mAh charging case. If you are in a hurry, a quick 10-minute charge provides about 4 hours of playback. The package comes with three sizes of ear tips (S, M, L) to ensure a secure fit for different ear shapes.
